Python统计文件夹各类文件数量，一键查看文件分类数量统计工具

前言

平时电脑文件夹里面文件繁多，图片、文档、视频、压缩包混杂在一起，想要知道一共有多少文件、每种格式分别有多少个，一个个手动数特别麻烦又浪费时间。

今天给大家分享一款非常实用的Python文件统计小脚本，不需要复杂配置，代码复制就能运行，可以自动统计文件夹下各类文件数量，分类展示，清晰直观，纯本地操作、无敏感内容，适合日常办公使用，也适合CSDN直接发布。

一、实现功能

自动遍历目标文件夹下所有文件
按文件后缀分类统计数量
展示每种文件格式的个数
统计文件夹总文件数量
内置模块实现，无需安装第三方库
运行速度快，统计结果一目了然

二、运行环境

仅使用Python内置 os 模块
无需额外安装任何依赖
Python3 全系兼容，Windows、Mac都能直接用

三、完整可运行代码

import os

def count_file_type(folder_path):
# 定义字典用来存放统计结果
file_count = {}
total_num = 0

# 遍历文件夹
for file in os.listdir(folder_path):
file_full_path = os.path.join(folder_path, file)

# 跳过文件夹，只统计文件
if os.path.isdir(file_full_path):
continue

# 获取文件后缀
suffix = os.path.splitext(file)[1].lower()
if suffix == "":
suffix = "无后缀"

# 统计数量累加
file_count[suffix] = file_count.get(suffix, 0) + 1
total_num += 1

# 输出统计结果
print("==========文件分类统计结果==========")
for k, v in file_count.items():
print(f"{k} 文件数量：{v} 个")
print("----------------------------------")
print(f"文件夹总文件数量：{total_num} 个")

if name == "main":
# 修改为你要统计的文件夹路径
target_dir = r"D:\Users\Downloads"
count_file_type(target_dir)

四、使用方法

新建py文件，将上方代码全部复制
修改代码里的文件夹路径为自己需要统计的目录
直接运行代码
控制台自动输出各类文件统计数量
